2017-03-07PCI: Prevent VPD access for QLogic ISP2722Ethan Zhao1-0/+1
QLogic ISP2722-based 16/32Gb Fibre Channel to PCIe Adapter has the VPD access issue too, while read the common pci-sysfs access interface shown as /sys/devices/pci0000:00/0000:00:03.2/0000:0b:00.0/vpd with simple 'cat' could cause system hang and panic: Kernel panic - not syncing: An NMI occurred.

2017-02-17PCI: Add ACS quirk for Qualcomm QDF2400 and QDF2432Sinan Kaya1-0/+23
The Qualcomm QDF2xxx root ports don't advertise an ACS capability, but they do provide ACS-like features to disable peer transactions and validate bus numbers in requests. To be specific: * Hardware supports source validation but it will report the issue as Completer Abort instead of ACS Violation. * Hardware doesn't support peer-to-peer and each root port is a root complex with unique segment numbers. * It is not possible for one root port to pass traffic to the other root port. All PCIe transactions are terminated inside the root port. Add an ACS quirk for the QDF2400 and QDF2432 products.

2017-02-08PCI: Add Broadcom Northstar2 PAXC quirk for device class and MPSSJon Mason1-0/+21
The Broadcom Northstar2 SoC has a number of quirks for the PAXC (internal/fake) PCI bus. Specifically, the PCI config space is shared between the root port and the first PF (ie., PF0), and a number of fields are tied to zero (thus preventing them from being set). These cannot be "fixed" in device firmware, so we must fix them with a quirk. Signed-off-by: Jon Mason <jon.mason@broadcom.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>

2016-12-12PCI: Enable access to non-standard VPD for Chelsio devices (cxgb3)Alexey Kardashevskiy1-0/+19
There is at least one Chelsio 10Gb card which uses VPD area to store some non-standard blocks (example below). However pci_vpd_size() returns the length of the first block only assuming that there can be only one VPD "End Tag". Since 4e1a635552d3 ("vfio/pci: Use kernel VPD access functions"), VFIO blocks access beyond that offset, which prevents the guest "cxgb3" driver from probing the device. The host system does not have this problem as its driver accesses the config space directly without pci_read_vpd(). Add a quirk to override the VPD size to a bigger value. The maximum size is taken from EEPROMSIZE in drivers/net/ethernet/chelsio/cxgb3/common.h. We do not read the tag as the cxgb3 driver does as the driver supports writing to EEPROM/VPD and when it writes, it only checks for 8192 bytes boundary. The quirk is registered for all devices supported by the cxgb3 driver. This adds a quirk to the PCI layer (not to the cxgb3 driver) as the cxgb3 driver itself accesses VPD directly and the problem only exists with the vfio-pci driver (when cxgb3 is not running on the host and may not be even loaded) which blocks accesses beyond the first block of VPD data. However vfio-pci itself does not have quirks mechanism so we add it to PCI.

2016-11-23PCI: Support INTx masking on ConnectX-4 with firmware x.14.1100+Noa Osherovich1-3/+56
Mellanox devices were marked as having INTx masking ability broken. As a result, the VFIO driver fails to start when more than one device function is passed-through to a VM if both have the same INTx pin. Prior to Connect-IB, Mellanox devices exposed to the operating system one PCI function per all ports. Starting from Connect-IB, the devices are function-per-port. When passing the second function to a VM, VFIO will fail to start. Exclude ConnectX-4, ConnectX4-Lx and Connect-IB from the list of Mellanox devices marked as having broken INTx masking: - ConnectX-4 and ConnectX4-LX firmware version is checked. If INTx masking is supported, we unmark the broken INTx masking. - Connect-IB does not support INTx currently so will not cause any problem.

2016-08-31thunderbolt: Fix resume quirk for Falcon Ridge 4C.Andreas Noever1-2/+1
The quirk 'quirk_apple_wait_for_thunderbolt' did not fire on Falcon Ridge 4C controllers with subdevice/subvendor set to zero. This lead to lost pci devices on system resume. Older thunderbolt controllers (pre Falcon Ridge) used the same device id for bridges and for the controller. On Apple hardware the subvendor- & subdevice-ids were set for the controller, but not for bridges. So that is what was used to differentiate between the two. Starting with Falcon Ridge bridges and controllers received different device ids. Additionally on some MacBookPro models (but not all) the subvendor/subdevice was zeroed. Starting with a42fb351c (thunderbolt: Allow loading of module on recent Apple MacBooks with thunderbolt 2 controller) the thunderbolt driver binds to all Falcon Ridge 4C controllers (irregardless of subvendor/subdevice). The corresponding quirk was not updated. This commit changes the quirk to check the device class instead of its subvendor-/subdeviceids. This works for all generations of Thunderbolt controllers.

2016-04-08thunderbolt: Support 1st gen Light Ridge controllerLukas Wunner1-1/+28

Consequently the chip suffers from some teething troubles: - MSI is broken for hotplug signaling on the downstream bridges: The chip just never sends an interrupt. It requests 32 MSIs for each of its six bridges and the pcieport driver only allocates one per bridge. However I've verified that even if 32 MSIs are allocated there's no interrupt on hotplug. The only option is thus to disable MSI, which is also what OS X does. Apparently all Thunderbolt chips up to revision 1 of Cactus Ridge 4C are plagued by this issue so quirk those as well. - The chip supports a maximum hop_count of 32, unlike its successors which support only 12. Fixup ring_interrupt_active() to cope with values >= 32. - Another peculiarity is that the chip supports a maximum of 13 ports whereas its successors support 12. However the additional port (#5) seems to be unusable as reading its TB_CFG_PORT config space results in TB_CFG_ERROR_INVALID_CONFIG_SPACE. Add a quirk to mark the port disabled on the root switch, assuming that's necessary on all Macs using this chip.
